This form of hosting is also commonly referred to as a “Virtual Server” or “Bulk Hosting” server because you purchase a set number of domains hosting accounts, or a set amount of disk space and bandwidth, and can manage it yourself without assistance of an Administrator. This gives you most of the control you would have if you had your own “Dedicated Server” without the high setup fees, and ongoing costs of maintaining your own equipment.In short you can also call is as mini server.
